Loops


It is believed that finger print patterns are inherited. The mode of inheritance is not known. One can reduce the data from three-way table to two-way table by collapsing the third dimension. It is expected that patterns on father's thumb are unrelated to those on mother's thumb. On the other hand patterns in child are expected to be related to patterns of either parent. One can also prepare 4*2 contingency tables. This can be used to test independence of child pattern from parent pattern combination. Another possible exploration is conditional independence. For example, is child pattern independent of mother pattern given father's pattern? Lastly, to test complete independence of all three dimensions, one must use the original 2*2*2 table.  


datasets

Collection of datasets as prepared by Profs. A.P. Gore, S.A. Paranjape, and M.B. Kulkarni of Department of Statistics, Poona University, India. With their permission, first letter of their names forms the name of this package, the package has been built by me and made available for the benefit of R users. This collection requires a rich class of models and can be a very useful building block for a beginner.
